"Naked agile is without apologies not for everyone and not for every project. Big, distributed teams can forget it (think Arctic naked skydiving ... cold cold cold). Life critical systems, forget it (think rocks and shale on the landing surface... death, destruction and many cuts). But if you're a small team, colocated, with access to usage experts, it could be your thing."

Anyone who tells you different is selling something," to quote Kent Beck.
